要約:	Title screen The reaction of various platinum metals (M = Ru, Os, Rh, Ir, Pd, Pt) with KBrF4 was investigated upon heating their mixtures to 400 °C. The formation of potassium fluorido platinum metallates in oxidation states +4 or +5, K2MF6 or KMF6, respectively, was observed in all cases. The obtained products were tested for their stability in water. Depending on the platinum metal, they were either stable, were reduced to the oxidation state +4, or were hydrolyzed to so far unidentified phases. K2RuF6, K2OsF6, α-K2PdF6, β-K2PdF6, which were previously only poorly characterized, were structurally reinvestigated by single crystal or powder X-ray diffraction, Raman and IR spectroscopy. The three former compounds crystallize isotypic in the trigonal, the latter in the hexagonal crystal system. The α→β phase transition of K2PdF6 was found to be reconstructive. Quantum chemical calculations were used to investigate the crystal structures. Режим доступа: по договору с организацией-держателем ресурса
